PROBLEM TO BE SOLVED: To provide a system for evaluating parallel motor control function in the brain.SOLUTION: The system evaluates motor control function in the brain from electromyogram information of the joint prime movers and information on the position, velocity and acceleration of the joint, wherein both pieces of information have been obtained by measuring a target-tracking movement performed by a subject with a motion measurement unit that tracks a moving target. The system comprises (a) a means for separating the frequencies of the electromyogram information and the frequencies of the information on the position, velocity and acceleration into a plurality of frequency components (b) a means for determining the ratio of viscosity coefficient to elastic coefficient (B/K ratio) for each of the frequency components by applying the electromyogram information and the information on the position, velocity and acceleration to a specific movement equation and (c) a means for evaluating the causal relationship between the motor control function in the brain and the target-tracking movement using the B/K ratio as an index.COPYRIGHT: (C)2011,JPO&INPIT【課題】脳内の運動制御機能を評価するシステムの提供。【解決手段】動く目標を追跡させる運動計測装置を用いて被験者に対し目標追跡運動を行なったときに測定された、関節の主動筋の筋電図情報並びに関節の位置、速度及び加速度情報から、脳内の運動制御機能を評価するシステムであって、(a)前記筋電図情報の周波数、並びに前記位置、速度及び加速度情報の周波数を複数の周波数成分に分離する手段、(b)前記筋電図情報並びに前記位置、速度及び加速度情報を所定の運動方程式に適用して前記それぞれの周波数成分について粘性係数と弾性係数との比(B/K比)を求める手段、並びに(c)前記B/K比を指標として、脳内運動制御機能と目標追跡運動との因果関係を評価する手段を含む前記システム。【選択図】図1
